i have a brand nerw out of the box supertigre GS40 engine, on a standard plane kit, now i have tryed to crank the engine over useing the guid that supertiger gives you... now the engine didnt start at all not even trying to, the glow plug heats up, fule gets to the piston i think im not sure how to check that, but i have noticed a leak where the prop meets the shaft the spins it, is this normal? i dont think it is but i danno. i have tryed everything but it just wont start, im going to take it back to my LHS to see what they can do but id rather not pay more for what i have already. any ideas would help heeps
